Snow: 9 inches expected in some areas

Old Man Winter isn't through with us yet. St. Patrick's Day started off snowy — a big change from the weekend when temperatures climbed into the 60s.

Some areas are expected to see as much as 9 inches, while others are only expected to get flurries, according to NBC10. Philadelphia is right on the edge of the storm, making it hard to predict total accumulation.

Snow began to fall late Sunday night and by early Monday up to 7 inches fell in parts of Sussex County, Del. and 6 inches in parts of Cape May County, N.J. Authorities activated the Delaware Emergency Operations Center at midnight Monday. Officials warned commuters that the morning commute could be treacherous and to avoid driving if possible.

A Winter Weather Warning is in effect for all of Delaware (New Castle, Kent and Sussex Counties) as well as most of South Jersey. Central and southern Delaware and South Jersey are expected to receive the most accumulation, while the Lehigh Valley won't see much if any accumulation at all.

The National Weather Service issued a Winter Weather Advisory for Burlington, Mercer, Middlesex and Monmouth Counties in New Jersey, and parts of Bucks, Chester, Delaware, Montgomery and Philadelphia counties in Pennsylvania. The advisory, which means periods of snow could cause travel difficulties as winds gust up to 25 mph, continues until noon Monday.
